what was that based on? 320?
yer mate, there prob are a few reasons for it but im not sure on them although 1 i think is to save weight and that this is a more revy engine. and i think that engine is based on the very rare 320is which knocks out about a 190bhp where as a 2.5 6cilinder only has 171 bhp
